THE MOVEMENT

How to perform

  1. Lie face down and secure a dumbbell carefully between the feet.
  2. Brace the hips against the bench or floor before curling.
  3. Bend the knees to bring the heels toward the body while keeping the dumbbell stable.
  4. Lower slowly until the hamstrings are lengthened.

IRONYOU / CORE

Core cues

  • Set the machine so the knee lines up comfortably with the pivot.
  • Keep the hips stable while curling the heel toward the body.
  • Control the return to a long hamstring position without letting the stack slam.

STAY SHARP

Common mistakes

  • Lifting or twisting the hips to finish the rep.
  • Using momentum instead of knee flexion.
  • Cutting the return short and losing the stretched position.
